The non-structural carbohydrates of kikuyu (Pennisetum clandestinum Hochst) seem to consist mainly of sucrose. Total non-structural carbohydrate content increased rapidly during the morning and reached maximum concentration in the afternoon. After sunset, the concentration decreased rapidly, reaching a minimum level by midnight. Low temperatures resulted in a significantly higher non-structural carbohydrate content in all plant fractions than at warmer growth temperatures. Non-structural carbohydrate concentrations were higher in stem tissue than in leaf material and the values were higher in 3-week than in 6-week regrowth.
